Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Verbinden von einem Werkzeug mit einem Halter über eine Spanneinrichtung.The The invention relates to a device for connecting a tool with a holder over a clamping device.
Stand der TechnikState of the art
Derartige Vorrichtungen sind in vielfältiger Form und Ausführung bekannt und auf dem Markt. Sie dienen vor allem zum Bearbeiten von Werkstücken innerhalb von Bearbeitungsstationen, wie beispielsweise Drehbänken, Fräsmaschinen od. dgl.such Devices are more diverse Shape and design known and in the market. They are mainly used for editing workpieces within machining stations, such as lathes, milling machines od. Like.
Aus
der
Als nachteilig bei dieser Vorrichtung hat sich herausgestellt, dass die Halterung des Werkzeuges in seiner Radialposition oft nicht ausreichend. Ist.When disadvantageous in this device has been found that the holder of the tool in its radial position often not sufficient. Is.

Aufgabetask
Aufgabe der vorliegenden Erfindung ist es, die radiale Festlegung des Werkzeuges an einem Halter zu verbessern.task The present invention is the radial fixing of the tool to improve on a holder.
Lösung der AufgabeSolution of the task
Zur Lösung der Aufgabe führt, dass in eine Ausnehmung des Werkzeuges eine deformierbare Hülse mit einer unrunden Innenkontur und in diese ein Drehelement mit einer unrunden Aussenkontur eingesetzt ist, wobei bei einem Drehen des Drehelementes dessen unrunde Aussenkontur im Zusammenwirken mit der unrunden Innenkontur der deformierbaren Hülse zu einem radialen Festlegen des Werkzeugs führt, wobei die unrunden Konturen gleich oder unterschiedlich sein können.to solution the task leads that in a recess of the tool a deformable sleeve with a non-circular inner contour and in this a rotary element with a Uncurved outer contour is used, with a turning of the Drehelementes its non-circular outer contour in cooperation with the non-circular inner contour of the deformable sleeve to a radial setting of the tool, where the non-round contours can be the same or different.
Der Vorteil dieser unrunden, deformierbaren Hülse ist es, dass sie durch das Drehelement so verformt werden kann, dass sie das aufgesetzte Werkzeug fest verspannt, sodass eine Radialbewegung des Werkzeuges unmöglich wird.Of the The advantage of this non-round, deformable sleeve is that it passes through the rotating element can be deformed so that it is the patch Tool firmly clamped, causing a radial movement of the tool impossible becomes.
Bevorzugt besteht die Hülse aus Metall, wobei selbstverständlich die Wandstärke der Hülse nicht allzu dick ist, sodass eine Deformation zugelassen wird. Ferner kann die Hülse direkt dem Halter angeformt werden, d. h., sie kann einstückig mit dem Halter hergestellt oder aber separat hergestellt und später durch geeignete Verbindungsmassnahmen mit dem Halter verbunden werden.Preferably, the sleeve is made of metal, of course, the wall thickness of the sleeve is not too thick, so that a deformation is allowed. Furthermore, the sleeve can be molded directly to the holder, ie, it can be made in one piece with the holder or separately manufactured and later by suitable Connection measures are connected to the holder.
In einem bevorzugtem Ausführungsbeispiel ist die Hülse querschnittlich mehreckig ausgestaltet, wobei der Begriff mehreckig übertrieben erscheint. Beispielsweise kann die Hülse dreieckig ausgebildet sein, wobei die Eckbereiche allerdings sehr stark abgerundet sind, sodass die eckige Ausbildung mit dem blossen Auge kaum sichtbar ist.In a preferred embodiment is the sleeve cross-sectionally polygonal designed, the term exaggerated polygonal appears. For example, the sleeve may be triangular, However, the corner areas are very much rounded, so the angular training with the naked eye is barely visible.
In dem erfindungsgemässen Ausführungsbeispiel sitzt die Hülse in einer Ausnehmung in dem Werkzeug. Bei dem Werkzeug kann es sich hierbei beispielsweise um einen Fräser oder auch um ein Sägeblatt handeln. Dabei ist die Ausnehmung des Werkzeuges selbst rund ausgestaltet. Wird nun ein Drehelement mit einer Aussenkontur ähnlich der unrunden Innenkontur der Hülse in die Hülse eingesetzt und gedreht, so geschieht eine Deformation der Hülse, wobei Hülsenbereiche gegen die Ausnehmung des Werkzeuges gedrückt werden.In the inventive embodiment the sleeve sits in a recess in the tool. The tool can be in this case, for example, a milling cutter or a saw blade act. The recess of the tool itself is designed around. Will now be a rotary element with an outer contour similar to the non-circular inner contour the sleeve in the sleeve used and rotated, so happens a deformation of the sleeve, wherein sleeve portions pressed against the recess of the tool.
Durch diese erfindungsgemässe Ausgestaltung entsteht eine sehr günstige Einspannung des Werkzeuges, sodass ein radiales Auslenken vermieden wird.By this inventive Design creates a very favorable clamping of the tool, so that a radial deflection is avoided.
